' ICE-CREAM-IBRICKING MACHINE.

To all whom it may concern Be it known that I, EDWARD J. RE'rzBAoH, a citizen of the United States, and residing at St. Louis, in the State of Missouri, have invented certain new and useful Improve- -ments in Ice-Cream-Bricking Machines, of

which the following is a specification.

This invention relates to machines for forming ice cream or the like in layers to form a multiple layer brick or the like.

In the manufacture of ice cream bricks, having a series of layers of different flavors, as now practised, the ice cream in semifrozen condition is spread in layers in a large "flat receptacle, the whole is then frozen stiff, and when frozen is cut up into bricks. The entire operation is performed by hand, thus necessitating a large amount of labor. he operation must necessarily be performed in the open air and in an open receptacle so that the ice cream is exposed and is liable to melt, thus resulting in a large percentage of waste. Furthermore this hand method is unsanitary.

One of the objects of this invention therefore is to construct a machine or' device which will form the ice cream or the like into a complete brick.

Another object is to construct a machine or device whereby the ice cream or the like is automatically deposited in layers to form a complete multiple layer brick.

Another object is to construct a machine which will form and discharge a brick without requiring handling of the ice cream during the formingoperation.

Another object is to construct a machine which will form and deposit a brick into a box or receptacle, which receptacle tended to retain the brick.

Another object is to construct a machine which will be simple in its. construction, automatic in its operation and sanitary, and further objects will a-ppear'from the detail description taken in connection with'the accompanying drawings, in which: F'gure 1 is a front elevation of a machine embodying this invention, showing the box support in lowered position, 7

. Referring to the accompanying drawings 10 designates a casting, which has cast integral therewith a plurality of cylinders 11 (in this case three) the casting being formed hollow to provide a jacket for the cylinders.

A plurality of conduits 12 (in this case three) extend up into the cylinders and are provided with flanges 13 for securing the conduits to the casting 10. -The necks or nipples 14 of these conduits are threaded as shown in Fig. 2, and the cylinders are provided with liners 15 screwed on the nipples 14, a gasket 16 being interposed to form a tight joint. The liners are provided with flanges 17 having holes 18 therein adapted to receive a wrench or other tool for removing and replacing the liners. A casting 18 1 cast integral with the conduits 12 is formed hollow to provide a jacket around the conduits, The lower ends of the conduits 12 are -located adjacently to form a series of adjacently positioned and oblong outlet or discharge passages 19 as shown in Figs. 1, 2 and 4. An inlet pipe 20 is connected to the lower end of the cylinder jacket and an outlet pipe 21 is connected to the upper end of this jacket. The conduit jacket is also provided with an inlet pipe22 connected to its upper end, and with afioutlet pipe-'23 connected to its lower end.

The cylinders receive pistons 28 provided with piston rings or other suitable packing, and each of these pistons is also provided with an air valve 29 opening inwardly and i normally retained in closed position by a spring as shown in 'Fig. 2. The pistons 28 are provided with piston rods 30 to a cross-head 31 by means of set screws 32. The hub 33 of the. cross-head is member 42 of the friction clutch is splined on the shaft 43 and is operated by a shifting lever 44. The screw is also provided with a hand wheel 45 whereby it may be operated manually. When the clutch is thrown into operation the power shaft 43 will rotate the screw 34 and move the pistons downwardly in the cylinders. The pistonscan be withdrawn by raising the cross-head by the hand wheel 45, or the shaft 43 may be provided with any suitable reversing mechanism. The parts are preferably so constructed that the pistons can be completely raised out of the cylinders by reversing the screw.

The casting 18 supports the casting 10 I through the conduits 12. -The casting 18 is in turn supported by brackets 50 from a table 51, which is in turn supported by brackets 52 from a base plate 58. A form 55, shown in detail in Figs. 8 and 9, is provided with a flange whereby itmay .be bolted or.

screwed-to the under side of the casting 18, the flange and casting being machined to make a good joint. Extending down from this flange are aplurality of spaced. blades three) 56 connected by an end wall 57, the other ends being leftopen as shown. The blades 56 and the endwall 57 thus form partitions is constructedto receive thereover a suitable receptacle, such as a standard ice cream box, as willbe hereinafter fully described. A pair of lugs 58 are formed on the lower face of the casting .18 and these lugs are provided with guideways for a cut-off slide 59, which is slotted as shown at '54 so as to slide across the form and against the end wall 57 to close the outlet from the conduits 12. The cut-ofi' slide is provided with a downwardly turned lug 60 whereby it may be operated.

The cut-off slide is normally held closed by means of springs61 secured at one of their ends to pins 62 on the casting 18 and at their other ends to laterally projecting lugs 63 on the cut-off slide 59, which lugs move in slots in'the lugs 58. Spring actuated latches 64 are adapted to hook over the lugs 63 when the slide is retracted, these latches being mounted upon extensions 65 of the lugs 58 fl and held in engagement with laterally extending pins 66 on the lugs 65. The latches 64 are connectedby a rod 67 extending across the machine so that both latches may be operated simultaneously to release the cut-off slide and permit it to close.

A skeleton frame 70 is mounted to slide on vertical rods or posts 71 supported between the cast lng 18 and the table 51, and

latches are arranged to snap over'the frame table 51 near the end of the downward this frame-is normally held in raised position by means of springs 72 mounted on the rods 71 between the frame and collars 73 seslide 59; so thatthese slides will belockedtogether when in the position shown in Figs. 2, 6 and 7, when they may be simultaneously opened and closed. It will be noted however, that while the cut-off slide 59 moves in stationary g'uideways; the cut-off slide 74 moves in guide-ways ona vertically movable frame 70. The slide 74 is otherwise of the same construction as the cutofl slide 59 as shown in Figs. 2, 6 and 7.

A box sustaining support or table 80 is mounted on vertical rods 81 passing through the table 51 and connected at their lower ends with and supported by a cross-head 82. Springs 83 on the rods 81 bear at their upper ends against the table 51 and at their lower ends against the cross-head 82 so as to normally-retain the support 80 in'lowered position as shown in Fig. 1. The support 80 is adapted to be raised through a link 84 connected to a readle 85 mounted upon the base plate 58. The support 80 has formed therein a recess 86 open at its frbnt end and closed at the back and sides by projecting portions 87 and 88 respectively. This recess is constructed to receive a standard ice cream box or receptacle 89 which is arranged to be pushed into place when the support 80 is in lowered position. The recess in the table positions the box in proper position underneath the form so that when the support 80 is raised by the treadle the box will be moved over the form. v

A pair of pivoted latches 90 are mounted on lateral extensions 91 on the support 80 so as to move therewith and the latches are normally moved inwardly into engagement with the stops 94 on the support 80 by means of springs 92. The latches are pro-. vided with tail pieces 93 adapted to engage the table 51 when the support 80 is lowered and throw the latches outwardly. These' 70 when the support is raised so that when the support is again lowered the latcheszwill carry the frame 70 with it to cause the slide 74- to move downwardly on the form and discharge the contents of the. form into the box as the box passes off of the form. When however, the support 80 with the box moves down, carrying the latches and the frame 7" with it, the tail-pieces 93 will engage the 313C movement of the support 80, and will throw the latches outwardly so as to release the frame and permit the springs 72 to move it back to raised position. The tail-pieces 93 are so constructed and positioned that the frame 70 will be released when the lower face of the cut-off slide 74 is just about flush with the lower end of the blades 56, or when the slide 74 has not quite passed off the form. It will be-noted that the pin 76, moves with the slide 74 in a downward direction but im--- i mediately engages with the aperture 77 when pump, and this jacket keeps the conduits and the form at a Warm temperature. The provision of the conduit water jacket is im- 7 portant, since it is found that ice cream in semi-frozen state will readilychange into a rigid state and will stick to and clog the conduits and the form. When however, the

conduits, the discharge passages thereof and the form are kept at a warm temperature then such sticking to the inside surface of the conduits will be prevented. It is obvious of course that the temperature of the water need only to be sufficiently high to prevent the freezing of the ice cream to the conduits and to prevent clogging. It will also be noted that the conduits increase in area toward their discharge end; this will also obviate and prevent clogging.

The cylinders or containers are filled with ice cream of different flavors in a semipears at the cut-off slides, and the clutch is i frozen state. To fill the machine, the crosshead is raised to withdraw the pistons out of the cylinders, and the pistons are again inserted after filling. The cut-off slides are released and held closed by the springs 61. The clutch is now thrown in and the pistons moved down until the ice cream apthen thrown out. A box 89 is'placed on the box support 80 and the support raised to place the box over the form, the supportbeing stopped by the engagement of its bottom with the bottom of the blades 56 of the form. The cut-off slides are now retracted vand locked in retracted position by the latches 64. The clutch is now again thrown in and the pistons moved down until the box is filled. The standard 37 may be provided with a scale and the cross-head 31 with a pointer so as to indicate the movement of the pistons, and this scale may be graduated for boxes of difierent depths and sizes. Af-

able manner, the cut-off slides are closed by I ter the box is filled, as indicated in any suitreleasing the latches 64, thereby cutting off I the supply of the ice cream to the box. The treadle 85 is now released when the springs 83 will operate to carry the support 80 down, the latches 90 moving with the table and carrying with them the frame and therefore the lower cut-off 74 so as to scrape theice cream off of the form and withdraw the box from the form. As the support 8U nears its lower limit the frame 70 and its cut-off slide 74 will be automatically released so as to move back into original position against the cut-off slide 59. The box can now be removed from the support and another box placed therein. These filled boxes are then placed in cold Storage and there frozen stiff. The boxes can be lined with tissue paper if so desired.

The ice cream is discharged from the separate cylinders or containers into theseparate' compartments formed inside of the box. The ice cream will therefore be deposited in separate adjacent layers separated by the inside separators or ribs 56. \Vhen the ice cream deposited in the box is withdrawn with the box from the form the ice cream is left in the box in layers. It will be understood that the separators 56 can be made thin, and the ice cream being in a semifrozen condition will unite into a solid brick. In order to compensate for the space taken up by the separators, and'in order to obtain a full box} the length of the blades 56 -is so'proportioned asv to leave a slight space between the upper end of the box and the lower face of the lower cut-off slide 74 as shown in Fig. 7, so that the box will be heaped and will therefore fill "Practically flush when the separators are withdrawn.

It will therefore be seen that the invention accomplishes its objects. The ice cream is deposited and formed into a multiple layer brick and is discharged in a condition ready to be sold in the box after it is frozen stiff. The operation of the machine is entirely au-' tomatic so that the formation of the bricks can be performed very quickly.

The liner 15, the conduits 1:2, and the form and its cut-off slidesare preferably constructed of a non-'corrodi-ble metal such as aluminum. This will keep the ice cream in a sanitary condition. In view of the fact that the ice cream is not handled at all af- 'ter being placed in the cylinders the device is sanitary in its operation. Since the ice cream is kept out of contact with the air,

this particular use, since it may be used where confectionery materials other than ice cream are to be formed into a multiple layer brick, cake or the like. It is therefore to be understood that the invention is not to be limited for use with ice cream.

While only one embodiment of this invention has been shown and described, it will be obvious that the invention may be embodied in different'forms. It is also obvious that various changes may be made in details of construction Without departing from this invention, and it is therefore to be understood that this invention is not to be limited to the specific construction shown and described; c
